Using Infrared Link
 Communicating with the CU
Put the BHT directly on the CU as shown below.
Interface connector
(The CU is available in
three models for the
RS-232C, Ethernet
(10Base-T), and USB
interfaces.)
 Communicating with other IrDA-compliant equipment
You can also have the BHT communicate with other IrDA-compliant equipment just
by aligning their IR ports with each other. The effective IR range and IR port angle
may differ depending upon the target equipment, so observe the instructions given
in manuals furnished with such equipment.
Shield the IrDA interface from direct sunlight, intense overhead lighting
(inverter-driven fluorescent lighting, in particular), and other potential
sources of infrared radiation. Sources to watch out for include remote
control units for television sets and the like.
